Overview
The TSZ182IQ2T is a dual operational amplifier produced by STMicroelectronics. It is part of the TSZ181 and TSZ182 series, known for their very low offset voltages and virtually zero drift versus temperature changes. These amplifiers offer rail-to-rail input and output, an excellent speed/power consumption ratio, and a 3 MHz gain bandwidth product while consuming only 1 mA at 5 V. The device also features an ultra-low input bias current, making it ideal for high-accuracy, high-bandwidth sensor interfaces.
